对农村中学物理教学来说,由于受到场地、经费、实验器材的限制,在一定程度上影响了学生学习物理的兴趣,失去学习物理知识的动力。在此,我们可以充分发挥低成本实验的优势,努力贯彻物理教学中以教师为主导、学生为主体、思维为核心、训练为主线、能力为目标的原则,进一步提高中学物理教学质量。 For rural middle school physics teaching, due to the restriction of venues, funds and experimental equipment, students’ interest in studying physics has been affected to a certain extent, and motivation of learning physics knowledge has been lost. Here, we can give full play to the advantages of low-cost experiments, and strive to implement the principle of teacher-led, students as the main body, thinking as the core, training as the main line and ability as the goal in physics teaching to further improve the quality of physics teaching in secondary schools.
